EXCLUSIVE: Jamie-Lynn Sigler Back on Set After MS Diagnosis, Overwhelmed by Positive Response

Jamie-Lynn Sigler is getting back to work, despite her battle with multiple sclerosis.

After revealing that she's been living with MS for the past 15 years, the 34-year-old actress is guest starring on Freeform comedy Baby Daddy. ET caught up with Sigler on show's set, whose stars welcomed her with open arms.

"It's been overwhelming in a good way," Sigler said, when asked about the response. "Everything that I feared about coming out about it has not happened. The complete opposite happened. I've been working consistently since, which is crazy."

Sigler says that she is "here and ready when the cameras are rolling," because she knows how to pace herself in order to last an entire work day.

"It's sort of like a gas tank," she said. "You have your amount of energy for the day, and you just sort of allocate and use it where you're going to need it."

"I actually called him my baby daddy, but now he's my husband," Sigler said. "We're four years into our relationship, so we didn't necessarily think it would be any different, but it is. It's fun to say husband and wife. We're a unit. We're a team. We always have been, but now it's just even more official and real."
